| * rtmpproto: Only prepend @setDataFrame for onMetaData and |RtmpSampleAccessMartin Storsjö2014-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when streaming to an RTMP server, any time a packet of type RTMP_PT_NOTIFY is encountered, the packet is prepended with @setDataFrame before it gets sent to the server. This is incorrect; only packets for onMetaData and |RtmpSampleAccess should invoke @setDataFrame on the RTMP server. Specifically, the current bug manifests itself when trying to stream onTextData or onCuePoint invocations. This fix addresses that problem and ensures that the @setDataFrame is only prepended for onMetaData and |RtmpSampleAccess. Since data is fed to the rtmp_write function in smaller pieces (depending on the calling IO buffer size), we can't generally assume that the whole packet (or even the whole command string) is available at once, therefore we can only check the command string once the full packet has been transferred to us for sending. Based on a patch by Jeffrey Wescott. Signed-off-by: Martin Storsjö <martin@martin.st>

Our ABI did not requires applications to only use threads (and matching ones) to what libavutil was build with Our code also was not affected by the leak this change fixes, though no question the atomics based implementation is not pretty at all. First and foremost the code must work, being pretty comes after that. If this causes problems, for example when libavutil is used by multiple applications each using a different kind of threading system then the default possibly has to be changed to the uglier atomics.

| * lavu: fix memory leaks by using a mutex instead of atomicswm42014-11-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The buffer pool has to atomically add and remove entries from the linked list of available buffers. This was done by removing the entire list with a CAS operation, working on it, and then setting it back again (using a retry-loop in case another thread was doing the same thing). This could effectively cause memory leaks: while a thread was working on the buffer list, other threads would allocate new buffers, increasing the pool's total size. There was no real leak, but since these extra buffers were not needed, but not free'd either (except when the buffer pool was destroyed), this had the same effects as a real leak. For some reason, growth was exponential, and could easily kill the process due to OOM in real-world uses. Fix this by using a mutex to protect the list operations. The fancy way atomics remove the whole list to work on it is not needed anymore, which also avoids the situation which was causing the leak. Signed-off-by: Anton Khirnov <anton@khirnov.net>
