Is this because it's an "old" codec that libavcodec have deliberately dropped, or is it a libavcodec "regression"?
Or is there something wrong with their equipment at nationaltv.ro?
Any ideas?
It might not even be a build issue - just an outdated codec that nobody uses. Except...

The Mediadirect servers belong to a TV Broadcasting company from Romania called Dolce TV, a company which has been broadcasting for about 2 years a free Web TV service for the Romanian citizens, consisting in about 30 national TV stations in .flv format. Its main rival, Ilink (AirTV) used to have both an IPTV and a WebTV service, both optimized for VLC (below version 1.0). Slowly, Ilink has sunk under, and right now Dolce might be taking over the IPTV market which has very few factors in its favor in Romania (cheap cable and satellite services, hundreds of local stations, and a high piracy factor - Ro is the only country with an actual number of about 70 TV channels pirate-broadcasting through Sopcast, some of them high-quality - they literally keep this P2p TV software alive).

Dolce TV might give up the free rtmp broadcast real soon and take over what's left of Ilink, directing their broadcast to VLC, and right now they might be working to "optimize" the streams in order to work with older VLC players (Air TV Romania is still reccomending VLC 0.8.6i to their users). Though RTSP and MMS broadcasts will be an unacceptable compromise to viewers.

I let it play longer now - every now and then the sound becomes metallic. There's also a desync. And given it's probably 100 per cent that they didn't do it on purpose, I have to go by your opinion: moronic coders.

Re: server trick?


well if you report it to ffmpeg with some sample file and figure out which revision broke it, they may fix it.

lots of work to track down bugs. but it can get things fixed.

Re: server trick?


I reported this bug to ffmpeg devs, along with a sample which reproduces the issue. Let's upvote this and hope that ffmpeg devs will fix this bug
